Topic: Firing on three.. (Read 512 times)

coming home from Bristol the bike started misfiring and four stroking and wouldn’t run clean until it hit 5k.. got home, stuck four new plugs in it and it’s still only running on 2,3 and 4 ( pipe cold on one) I guess the next thing is to swap the other lead coming out of the same coil and if it’s still not firing on one it’s simmat I’ve done with the ivanising..😟

That's a bugger Paul!!!If it was an ivansing fault wouldn't it have manifested itself on the previous rides you've had after doing it?

How are the front forks after Monday? Feeling good I hope.I haven't had the chance to take mine out yet and I'm away from tomorrow afternoon until Monday at Hard Rock Hell Metal at the O2 Academy in Birmingham, so I will have to wait a bit longer until I can get me knee down

checked the fuel in the float bowls of one and two by draining them into a aerosol can top and measuring and it was 5mm higher in one so hoping your right mike. have pulled the carbs and changed the o ring, checked over float heights et too ill put it all back tomorrow hopefully its sorted. the old o ring was undamaged but definitely weaker/softer, hoping if thats what is the problem the rest will be ok but if another goes i'll change them all for genuine yam items

just got back from walking the dog gonna go put the carbs back on once ive had some cawfee..think i'll take no1 mixture screw out and just blow out the pilot circuit as well just in case I didn't get it all clean enough when I drilled the bypass holes. Ive realised the thing to do when taking these carbs on and off is not look at is as chore, just treat it as enjoyable maintenance, take my time and don't try to rush and make it hard work. Fourth time in and out now lol so im getting quite philosophical about it

it was either a faulty o ring on the inlet valve or a bit of muck in the pilot circuit. I took the mixture screw out and the pilot jet and blew through with compressed air and I thin a bit of debris came out initially but I cant honestly say im sure as it was literally a little black puff of summat then it was clear. I also changed the o ring on the inlet valve on cylinder no1 carb. I think that because when I measured the petrol that came out of no1 carb it was 5mm higher on the ruler than no 2 its more likely to be the o ring as Mike said.

Lol aint that the truth! yeah ta mate I hope so too.that last time, to give me a point of reference I changed the o ring in no 4 too. that way if cylinder 2 or 3 go the same way i'll know the pack of o rings I bought are prematurely failing. Im hoping it was either just a dodgy o ring or perhaps I didn't exercise enough care fitting it.I do remember back when I ivanised trying to refit the first one I didn't use silicone grease on the alu body the ring sits around initially, and it wouldn't push in. I then greased it and fitted it, but I should have changed the o ring first as I could have guillotined a tiny bit off its tiny outer ring face perhaps. It was at the end of the bank where I started so theres a fifty/fifty chance it was cylinder no1.Im getting to really know my bike at least lol. I kinda like that. And on the shakedown run yesterday with a new bt016 on the rear and refreshed front forks and calipers, I was reminded just how brilliant this bike is. I'll never sell it. Why would I? as it gets older i'll just keep on top of maintenance. Shes worth it...

I had to smile when I read your list of wrinkles you've learned to make getting the carbs out easier. They're all in the Noddy's Guide I wrote a while ago but they don't really register when you read them and only make sense after you've done the job a few times.

My miley 1000 has just done the same to me. Started running on 3, number 2 pipe isn't getting hot.

Iridium plugs aren't cheap thought it may be a plug, don't know when they were last done.

If I get stuck, could I hit you up for some advice? I think I'm fairly local to you and it would be usefulto compare with the same bike. My exup is also apparently pinned open and I'm curious about if it's worth getting it working again.
